Redshift
Redshift 是一个昼夜节律照明工具和色温控制器，旨在使屏幕输出与自然光周期保持一致。它充当 X11 环境的显示管理器，根据一天中的时间和地理位置调整屏幕色温，以减少眼睛疲劳。
该软件通过使用存储的坐标计算太阳位置来自动调整显示照明，从而将屏幕颜色从蓝色调向暖色调偏移。它还通过操纵伽马斜坡来充当屏幕亮度管理器，以便在硬件背光控制不足时模拟精确的亮度级别。
该系统利用守护进程-客户端进程模型来管理后台更新，并提供用于温度控制的图形状态图标。用户设置和地理坐标通过配置文件进行维护，以确保跨会话的一致行为。
Features
- Color Temperature Managers - Adjusts the screen color temperature to shift from blue to warmer tones based on time and location.
- Circadian Lighting Automation - Automates screen color and brightness shifts to align with natural light cycles.
- Circadian Lighting Tools - Functions as a system for automating display color shifts to align screen output with natural light cycles.
- Gamma Ramps - Manipulates hardware gamma ramps to precisely control screen color temperature and brightness.
- Time-Based Event Scheduling - Automates color temperature transitions by scheduling updates based on the system clock.
- Geographic Temperature Calculation - Calculates the ideal screen color temperature based on the user's geographic coordinates and the sun's position.
- Visual Fatigue Reduction - Reduces visual fatigue and sleep disruption by filtering high-energy blue light.
- Display Gamma Management - Manages perceived screen brightness via gamma ramp manipulation to supplement hardware backlight controls.
- X11 Gamma Manipulators - Manipulates screen gamma and color profiles specifically for Linux X Window System environments.
- Daemon-Client Structures - Employs a daemon-client architecture to separate background display updates from the user control interface.
- Hardware Brightness Management - Manages perceived screen brightness through software-level gamma adjustments.
- Brightness Level Adjustments - Simulates precise brightness levels by manipulating gamma ramps when hardware controls are too coarse.
- System Utilities - Adjusts screen color temperature based on surroundings.
